CUSTOM ROM
A custom rom is an Android system which is modification of a stock rom (System which comes with your new phone by default).

Performance
Out of the box, your phone or tablet’s hardware is clocked at a speed that the manufacturer considers optimal in terms of heat and battery life. On a custom ROM, you’ll be able to overclock your hardware to get big performance increases. These changes can really show when you’re playing graphics intensive games. Another way a ROM can improve performance is by removing carrier or OEM-installed apps, known as bloatware, which can free up system resources.

Battery Life
On the flip-side of overclocking, there’s underclocking. If you don’t really need all the speed of your massive processor, you can dial it back a bit by underclocking. With your processor running at a lower speed, you can often extend battery life by days! This is something to consider if you find yourself charging your phone multiple times per day. A custom ROM, again, by removing bloatware, can help free up the CPU to do less because there are fewer apps running in the background.

Updates
One of the most frustrating things about owning an Android is waiting for your manufacturer to push an update to your phone so you can get the latest features. Often times manufacturers will even cut support for your device entirely. This leaves you stuck with a phone with an old version of Android. The solution is a custom ROM on the newest Android version. Even if your phone is stuck on KitKat, you can download and flash a ROM based on Lollipop. Many of the more popular ROMs even update on a daily basis. These updates are called “Nightlies”.

Customization
Android is already very customizable right out of the box. With a custom ROM you can even modify things like the color of your notification light, the force of your vibration, the saturation of the colors on your screen and much more. I wish I could customize myself a friend!
